thanks for all the work you put into ubu, it has kept my trusty z77 board up to date for over 1 year.

I recently updated my VBIOS following your guide and I have a question:How can I tell if I actually updated the vbios ? If I compare the vbiossib.dat I created myself with the vbios.dat that I extracted from my original BIOS, the MD5 sum is identical.If I open both files in the Intel BMP utility, VBT version is also identical (174). I have the ASRock Z77 Pro4, is it possible that the vbios from the latest official BIOS is the latest one ?I have an Ivy Bridge 3570k CPU. I already updated the entire BIOS with ubu (my modified vbiossib.dat was present in modules\vga in ubu folder) and the Board and iGPU are working fine.

Thanks for the help. I'm using main BIOS 9903 though, it was provided to me by ASUS as a beta BIOS to fix the EFI boot issue I was having. If it contains the same extracted vBIOS as main BIOS 3601, can I simply use the v2170 OROM that you modified?
